AUTOMATIC CUT-OFF.

Specification of Letters Patent.

Patented Mar. 16, 1915.

Application filed April 30, 1913, Serial No. 764,724. Renewed August 11, 1914. Serial No. 858,287.

To all 1.071 0m it may concern:

Be it known that I, Janus E. humans, a citizen of the United States. residing at Strong City, in the county of Roger Mills and State of Oklahoma, have invented a new and useful Automatic (ut-Ofi", of which the following is a specification.

The device forming the subject matter of this application is a cut-off; adapted to be assembled with the down-spout of a conductor. leading from the roof of a building or other structure, the device being adapted to control the flow of rain water from the roof of the building automatically, into a cistern or like container. or to discharge the Water outside of the cistern.

One object of the present invention is to provide novel means for controlling the movement of the valve which directs the water to the filter and into the cistern or away from the filter.

Another object of the invention is to provide novel means for depositing a portion of the water in a receptacle whereby the valve is actuated.

It is within the scope of the invention to improve generally and to enhance the utility of. devices of that tvpe to which the present invention appertains.

With the above and other objects in View which will appear as the description proceeds. the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. it being understood that changes in the precise embodiment of in ention herein disclosed can be made within the scope of what is claimed without de arting from the s irit of the invention.

In the drawing:Figure 1 shows the invention in longitudinal section: Fig. 2 is a transverse section on the line 2-2 Fig. 1; Fig. 3 is a transverse section on the line 33 of Fig. 1; Fig. 4 is a transverse section on the line 44 of Fig. 1; and Fig. 5

is a perspective of the valve.

In carrying out the invention. there is provided a casing 1 the top of which, denoted by the numeral 2, is fashioned in two parts, held in place by a locking bar 50 the bottom of the casing 1 being denoted by the numeral 3. Extended across the casing 1 is a curved plate 51 supporting a detachable inlet 4 which may communicate with the downspout of a conductor pipe leading to the roof of a building, the parts of the top 2 meeting around the periphery of the nlet. Located within the casing lies an upright partition 5 dividing the casing 1 into compartments 6 and 7. Entering the casing 1 and communicating with the comtsemi-circulartransverse outline is secured along its longitudinal edges of the partition 5. The upper end of the tube 9 is spaced above the upper end of the outlet 8 and the lower end of the tube 9 is spaced above the bottom 3 of the casing 1. The lower portion of the compartment 6 may be filled with filtering material 10. the lower end of the tube 9-extending downwardly into the filtering material.

Located in the com artment 7 and ex ending transversely of the same is a deck 11. forming a compartment 33. 'A downwardly extended tube 12 is secured to the deck 11 and the lower end of the tube 12 is closed by a pert-ovate p attorm 14. The extreme lower" end of the ube 12 is closed by a bottom 15. Entering the casing 1 and communicating with the s ace between the lat orm 14 and the bott m 15 is an outlet pipe 16. Thereis an opening in the deck 11 surrounded by a de ending iacket 17. Qecured within the iacket 17is a spiral deflec or 18. A nozzle 19 passes th ugh the bottom 15 and surrounds one oi the perf rati ns in the platform14. A tubular guide 20 passes. throng-ii the deck 11. through the pla form 14 and through the bottom 15. A r d 21 is looselv moun ed in the guide 20 to slide therein. A receptacle 22 is pivotally secured to the lower end of the rod 21 andlies within the com artment 33.

The upper end of the rod 21 is secured to the intermediate portion of the lever 23 attached to a shat't 24 which is mounted to rock in the partition 5. One end of the lever 23 protrudes into the compartment 6 and is provided with a slidable counterweight held in place by a locking screw 25". Secured to the shaft 24 and located approximately at right angles to the lever 23 is a valve 26, which is shown in detail in Fig. 5. The valve 26 may be of any desired form,

but in the present instance, it is fashioned from a plate 27 which is notched in its edges, the edges of the plate being turned in opposite directions to'forin outstanding wings 28. The plate 27 is bent transversely, intermediate its ends as shown at 29, to bring the ends of the plate together. The shaft 24 is secured between the ends of the plate 2'7. The deflector 26 above described, stands in the position shown in Fig. 1, and the parts of the top 2 of the casing 1 are equipped with depending stops 30 adapted to engage the upper edge of the deflector 26. to limit the swinging movement of the deflector in opposite directions. The stops 30 are located close to the side walls of the inlet 4-.

In the receptacle 22 there is a very small hole 31 and another hole 32 is fashioned in the casing 1, adjacent the bottom 3 thereof. These holes 31 and 32 are of so small diameters, that although they constitute means for draining the respective elements in which they are located, this draining takes place so slowly as not to affect the operation of the structure, except under conditions specifically pointed out hereinafter.

In practical operation, the parts are positioned as shown in Fig. 1. Then, the rain water entering the inlet will be engaged by the deflector 26 and be projected upon the deck 11. From the deck 11, the water will flow downwardly, through the jacket 17. The spiral deflector 18 which is located within the jacket 17, serves to give a whirling movement to the water, so that the water, as it emerges from the lower end of the jacket 17 is distributed evenly over the perforated platform 14. The major portion of the water thus deposited upon the perforated platform 14: will pass through the perforations therein and run away through the outlet 16. For a considerable space of time, the parts will remain as shown in Fig. 1, the water flowing away by means of the outlet 16. As a consequence, the water which falls during the earlier part of a storm and which contains the impurities found upon the roof, will be conducted away. It is to be observed, however, that a small portion of the water which falls during the earlier portion of the storm will be directed by the nozzle 19 into the receptacle 22. By adjusting the counterweight 25 properly upon the lever 241-, the lever may be made to tilt, at a predetermined time, under the weight of water accumulated in the receptacle 22. When the receptacle 22 and its contents have attained a sufficient weight to tilt the lever 23, the valve 26 will be swung to the right, referring to Fig. 1, until the upper end of the valve comes into contact with the right hand stop 30. Then, the water entering the inlet 4 will be received by the valve 26 and will be thrown against the side wall of the tube 9. The water will pass downwardly through the tube 9 into the filtering material 10, and then upwardly through the filtering material, the water draining away through the outlet 8 into the cistern or other container which is provided for the purpose of receiving the filtered water.

It has been stated hereinbefore that the receptacle and the casing 1, respectively, are provided with very small openings 31 and 32. The opening 81 in the receptacle 22 permits the accumulated water therein to drain away slowly. The opening 31 may be of almost microscopic diameter, and after a period of time ranging from a quarter of an hour or so to several days, the receptacle 22 will loose its contents and become relatively light, whereupon the counterweight 25 will tilt the lever 23 and restore the valve 26 to the left hand position shown in Fig. 1. Thereupon the cycle will be repeated automatically. It is of course obvious that the hole 32 permits the water which runs out of the receptacle 22, to drain out of the compartment 33.

The spiral deflector 18 which is located within the jacket 17 is of peculiar importance, since it secures an even distribution of the water over the perforated platform 1 1, and regulates, properly, the loading of the receptacle 22, to effect a tilting of the lever 23 in the manner hereinbefore set forth. The deflector 18 is given a comparatively slow twist. The water, therefore, does not pass through the deflector at a high rate of speed and acquire sufficient momentum to throw all of the water outwardly around the edge of the platform. As a consequence, an even distribution is effected.

Having thus described the invention, what is claimed is 1. ln a device of the class described, a casing having an inlet and comprising a platform provided with openings; a fixed deflector located above the platform and above the openings, the deflector comprising means for spreading material over all of the openings at once; a receptacle into which one of the openings discharges; a valve supported by the casing and constituting means for directing material from the inlet toward and away from the deflector; and means for operatively connecting the valve with the receptacle.

2. In a device of the class described, a casing having an inlet and provided with a platform having openings; a spiral deflector held above the platform; a valve carried by the casing and adapted to direct material from the inlet toward and away from the deflector; a receptacle located below the platform and operatively connected with the valve; means for conducting the mate rial from one of the openings in the platform, into the receptacle; and means for conducting the material from the other opening away from the receptacle.

- 3. In a device of the class described,'a casing provided with an inlet and with; an outlet; a perforated platform located in the casing above the outlet; a nozzle communicating with one of the perforations of the platform; a receptacle into which the nozzle discharges; a jacket supported in the casing above the platform; a spiral deflector located in the jacket; a valve controlling the e inlet and movably mounted in the casing; means for operatively connecting the valve with the receptacle; the valveconstituting 1 means for discharging material Within and outside of the jacket.

In testimony'that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two Witnesses.
